This article focuses on "how to write a shell script to test the download speed". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to write a shell script to test the download speed.

Test the download degree with Shell under Linux. The code is as follows:

The code is as follows:

#! / bin/bash

# date:20140210

# used for test server download speed

Ritual host = "188.18.28.19"

Ringing dirt = "/ home/test0208/tmp"

Ringing file = "$r_dir/ddfile2m"

Lumped dirt = "/ home/yangjuying/tmp"

Lumped file = "$l_dir/ddfile2m"

Lumped log = "$l_dir/182.18.28.19-download.log"

Echo "- $(date +% Y%m%d-%H%M%S) -" > > $l_log

Start_t= "$(date + s)"

Scp-P22-o connecttimeout=10-o GSSAPIAuthentication=no test0208@$r_host:$r_file $l_file > > $l_log 2 > & 1

Rc= "$?"

If ["$rc"-eq 0]; then

Stop_t= "$(date + s)"

File_stat= "$(stat $l_file)"

File_ctime= "$(echo" $file_stat "| awk-F" [.] "'FNR==5 {print $2 camera 3}' | sed's / [-:] / / g')"

File_ct= "$(awk-v t =" $file_ctime "'BEGIN {print mktime (t)}')"

File_size= "$(du-sm $l_file | cut-F1)"

Rm "$l_file"

Else

Stop_t= ""

Fi

If [- n "$stop_t"]; then

Connect_t=$ (($file_ct-$start_t))

Transfer_t=$ (($stop_t-$file_ct))

All_t=$ (($stop_t-$start_t))

Speed= "$(echo" scale=3;$file_size/$transfer_t "| bc)"

Echo "size:$ {file_size} MB, all_time:$all_t, connect_time:$connect_t, transfer_time:$transfer_t, speed:$ {speed} MB/s" > $l_log

Else

Echo "scp error!" > > $l_log

Fi
